CONNECTION FOR FLUID-SUPPLY PIPES.

SPECIFICATION forming part of Letters Patent No. 782,908, dated February21, 1905.

Application filed April 18,1904. Serial No. 203,684.

7 dock, Allegheny county, and State of Pennsylvania, have invented a newand useful Improvement in Connections for Fluid-Supply Pipes, of whichthe following is a full, clear,

and exact description, reference being had to the accompanying drawings,forming part of this specification, in which- Figure 1 is a plan of atraveling chargingmachine mounted on a track and equipped with myimproved pipe connections for supplying motive fluid to the machine.Fig. 2 is an end elevation of the traveling machine with the improvedpipe connection shown in vertical cross-section.

The object of my invention is to provide a system of piping forconducting steam, air, water, or other fluids from a stationary point ofsupply to a laterally-variable pointof use and in providingmeans forbalancing the movable pipe and reducing the power necessary to move itby the traveling machine.

The invention is especially designed for use with apparatus for chargingand drawing horizontal heating-furnaces, in which the apparatus ismounted on a track parallel with and in front of a row of such furnaces.

It consists in a movable pipe attached to and moved by the travelingmachine and arranged to telescope with stationary pipes, with the endsof the movable pipe projecting into the larger stationary pipes throughsuitable stufling-boxes and glands, which make fluidtight slidingconnections between the movable and stationary pipes, and in suitablesupports to prevent sagging of the movable pipe The stationary pipes at4, with the movable pipe 5, are located on the outside of the track-"rail 3, the movable pipe being supported along its length by suitableidler-wheels 6.

On the outer ends of the stationary supply-pipes are suitable heads 77,in one of which is a connection leading to the fluid-supply. Onthe innerends of the stationary pipes are stur'iingboxes 8 8, having glands 9 9and packing 10 10, through which the ends of the movable pipe alwaysextend. At about the center ot'its length the movable pipe is attachedto the traveling machine, and through suitablepipes 11 12 the movablepipe is connected with the motive cylinder 13, mounted on the travelingmachine.

By the use of my improvement the cost of the apparatus for supplyingmotive fluid to the charging-machine is greatly reduced. Thestufling-boxes on the ends of the stationary pipes act as guides for themovable pipe. Both ends of the movable pipe being open, the pipe isbalanced by the fluid-pressu re, and the power required to move the pipeis reduced. Theidler-rollers support the movable pipe and preventbending or sagging and consequent bihding in the stuffing-boxes. Therebeing but two sliding connections, both of which are outside packedjoints, which are easily and quickly repaired or renewed, the loss fromleakage and cost of repairs are greatly reduced and delays caused bymaking of repairs are avoided.

Variations may be madein the construction of the apparatus withoutdeparting from my invention, since What 1 claim is 1. The combinationwith a traveling machine of a fluid-supply leading thereto, andcomprising two stationary pipes in endwise alinement and an intermediatemovable pipe extending into the stationary pipes, said movable pipehaving a sliding connection with the stationary pipes and being movablewith the machine, and a fluid-outlet leading from the traveling pipe tothe machine; substantially as described.

2. The combination with two stationary pipes in endwise alinement, of anintermediate movable pipe having telescoping connection with bothstationary pipes and receiving fluid from one of them, said movable pipehaving an outlet, and a traveling machine moving with the movable pipeand having fluid-supply connection therewith; substantially asdescribed.

In testimony whereof I have hereunto set my hand April 15, 1904.
